Disappearing Building

ABSTRACT

A building equipped with a suitable mechanism by which it is caused to descend in a suitable shaft below ground level, in order to secure it both against bad atmospheric occurrences and malicious acts, is disclosed.

BRIEF DESCRIPTION OF THE INVENTION

The object of the present Invention comprises a building equipped with a suitable mechanism by which it is caused to descend into a suitable shaft below ground level, in order to secure it in the event of prolonged absence of the occupants, both against particularly bad atmospheric occurrences e.g. hurricanes, floods and fires, and to avoid, or at least limit, malicious acts of intrusion, theft or damage.

The building of the present invention is generally a house, a shop, a kiosk, a laboratory, a workshop, an exhibition hall characterized by not having any protuberances, having limited dimensions both in floor space and in height and being constructed preferably in wood or prefabricated material.

It is suggested, as a preferred example, wooden or prefabricated houses comprising a single floor and having floor dimensions in the order of a few square metres, e.g. 30-50 m², without balconies or verandas.

STATE OF THE ART

In the current state of the art, no buildings analogous to the present invention currently exist.

DESCRIPTION OF THE INVENTION

The object of the present invention comprises a building and an underlying shaft of slightly larger dimensions of floor space and height than the building, also an apparatus to cause the transport of said building, positioning it into the shaft and lifting it out thereof. The underlying shaft to accommodate the building will be finished with flooring and lateral walls to contain the ground, and these may be of cement, bricks or other materials. Said shaft is not covered, said building functioning as a cover. Generally speaking it is advisable that the lateral walls of the underlying shaft protrude at least 50 cm above the surrounding ground level and, in the case of sloping land, protrude 50 cm above the most elevated point of the surrounding ground level.

Four jacks cause the vertical transport of the building, one at each corner of the shaft, fixed to the base of the building. Said jacks are electrically operated but can also be operated with power supplied by an internal combustion engine. The jacks may be rack and pinion but, according to specific requirements, screw jacks, piston jacks, hydraulic jacks or compressed air operated jacks may be used. The building must be constructed with a suitable supporting base capable of supporting the necessary raising force of the four jacks. Preferably a site with flat ground or with a slight slope will be chosen for the construction of the building.

In the position of maximum elevation, the floor of the building corresponds with the highest extremity of the walls of the underlying shaft, that being 50 cm above ground level and, if the ground is inclined, 50 cm above its most elevated point. In this position it is advisable, for safety, to place blocking devices on each of the four sides, comprising, for example, four iron bars which are positioned under the floor of the building and which extend into the walls of the underlying shaft, actuated electrically, hydraulically or even manually. All external connections of the building, such as mains services, comprising for example, connections for electricity, drinking water, sewage, telephone, gas etc., can be made with flexible pipes. Alternatively, the electrical connections can be equipped with suitable detachable sockets and the water and gas connections can be equipped with suitable valves. With the action of placing the building in safety, the four safety blocking devices and all the external services connections, if not flexible, are retracted, as are, if necessary, possible external antennas.

When the building is in its position of use, that is completely outside the containing shaft, a suitable cover is provided for the small gap existing between the top side of the internal perimetric walls of the shaft and the external perimetric walls of the building to prevent the ingress of dust, leaves and small animals. On the exterior, in the immediate vicinity of the building, is also provided an appropriate protected electrical panel for the actuation of the blocking devices and the jacks as well as suitable signs to prevent damage to third parties or to the building itself. A retractable folding ladder is provided, fixed to the floor of the building, to access the underlying shaft; the shaft floor is suitably inclined towards a drain with soakaway or equipped with a pump for the removal of possible water accumulation in the shaft. A suitable space is made between said floor and the lower surface of the building to accommodate the jacks and the retractable ladder.

DESCRIPTION OF SOME PREFERRED EMBODIMENTS OF THE INVENTION

In one embodiment of the building object of the invention, when said building has a structure such as to be able to be lowered completely, roof included, into the containing shaft, a cover is provided comprising a sheet of impermeable and fireproof material, which is spread over the roof of the building placed in safety, and suitably fixed to the ground (FIG. 14).

Alternatively to the above mentioned embodiment, in the case where it is deemed suitable to excavate to a lesser depth, and therefore the building is admitted into the containing shaft with the exclusion of the roof, this roof of fireproof material and equipped perimetrically with a suitable band of impermeable, fireproof and elastic material which abuts against the top of the lateral walls of the shaft when the building is placed in safety in the underlying shaft, closing the gap between roof and lateral walls of the shaft (FIG. 5-8).

In another embodiment of the invention, when the building to be admitted has a roof, constructed in fireproof material, that projects over the corresponding lateral walls of the building, to avoid damage to the eaves of the roof against the top of the shaft walls during descent into the underlying shaft, suitable stops are provided to ensure a suitable distance between the eaves of the roof and the top of the shaft walls. To protect the gap created between the eaves of the roof and the top of the shaft walls, the eaves are shaped as a skirt so that the latter, when the building is placed in safety, closes the lateral walls of the shaft. The external vertical sides of the containing walls conveniently channel rainwater to their exterior (FIG. 9-12).

In another embodiment the building according to the invention, is equipped with a flat sheet steel roof, easily insulated at its exterior and easily reinforced and equipped with vertical sides. Said sides are easily sized and positioned so that when the building is placed in safety in the underlying shaft, the vertical sides of the roof close the external lateral wall of the shaft, like a box. In such position, suitable blocking and security apparatus can securely enclose the building in the underlying shaft. The external vertical sides of the containing walls easily channel rainwater to their exterior (FIG. 13-16).
